Growth in plants occurs through cell division and cell expansion. Cell division allows for the formation of new cells, while cell expansion allows the cells to increase in size. This growth is regulated by hormones such as auxins, cytokinins, and gibberellins. These hormones control processes such as cell elongation, cell differentiation, and overall plant development. Ultimately, growth in plants is a complex process that involves the coordination of various cellular and molecular mechanisms. **

Growth lights are not always necessary for plants, as they can thrive with natural sunlight. However, in indoor settings or areas with limited sunlight, growth lights can be beneficial for providing the necessary light spectrum for photosynthesis. Different plants have different light requirements, so it is important to research the specific needs of the plants you are growing to determine if growth lights are necessary. **

Several factors can hinder the growth of plants, including inadequate sunlight, poor soil quality, lack of water, pests, diseases, and extreme temperatures. Insufficient nutrients in the soil can also stunt plant growth, as can overcrowding or competition with other plants for resources. Additionally, environmental pollution and human activities such as overfertilization or overwatering can negatively impact plant growth. **

No, plants do not only store water during growth. They also store water as a way to survive in times of drought or when water is scarce. Plants have specialized structures like vacuoles and cell walls that help them store water for later use. Additionally, some plants have adaptations like succulent leaves or stems that allow them to store water for extended periods. **

The growth period in plants refers to the phase in a plant's life cycle when it experiences rapid development and increase in size. This period typically occurs during the spring and summer months when plants have access to sunlight, water, and nutrients needed for photosynthesis and growth. During this time, plants produce new leaves, stems, and roots, and may also flower and produce fruits. The growth period is crucial for plants to build up their energy reserves and prepare for the upcoming seasons. **

The growth of aquarium plants can vary depending on the species and the conditions in the aquarium. Generally, aquarium plants require proper lighting, nutrients, and carbon dioxide to grow. With the right conditions, aquarium plants can grow quickly and fill out the tank, providing a natural and beautiful environment for fish and other aquatic life. Regular pruning and maintenance may be necessary to control the growth and keep the aquarium looking its best. **

Growth in plants cannot occur without mitosis because mitosis is the process by which cells divide and multiply. During mitosis, the cell's genetic material is replicated and then divided equally between two daughter cells, allowing for growth and repair of tissues. Without mitosis, plants would not be able to produce new cells and therefore would not be able to grow. Additionally, mitosis is essential for the development of roots, stems, leaves, and flowers in plants, making it a crucial process for overall plant growth and development. **

No, plants do not only store water during their growth. While water storage is important for plants to survive periods of drought or limited water availability, they also store other nutrients and energy reserves in various parts of their structure. For example, plants store carbohydrates in the form of starch in their roots, stems, and leaves, which they can use as a source of energy when needed. Additionally, plants also store other essential nutrients such as nitrogen, phosphorus, and potassium in their tissues to support their growth and development. **
